I was asked to draw the graph of y=cosx-2
This equation means the graph of y=cosx is shifted 2 units down correct? (Since -2 is the C value because if it were the d value in y=acos(k(x-d))+c it would be in degrees, so we shift each y coordinate down 2 units, or subtract the y value by 2, i have graped the equation, it makes sense but when i put it in the graphing calculator it shows a different graph, infact it shows y=cosx-2 to be the EXACT same graph as the one from y=cosx...
when i put those 2 equations in it shows 1 graph (or rather the 2 graphs on top of each other)
I suspect i am correct because my instincts never let me down and the graphing calculator probably has some settings wrong
who do you think is correct?
